LM5046: Total operating current estimation

MINKYUNG KIM

Part Number: LM5046

Hello team,

Could you please help me with estimation of max. supply current of LM5046? Customer requires this spec to set up their power supply spec/manual.

1. Customer asked I_CC max spec. I don't think this parameter represents total operating current of LM5046. Can you advise it?

2. If I_CC is not a right parameter for total operating current, how can I estimate total operating current of LM5046?

Thank you for your prompt response.

Hi Yunsheng,

Thank you for reply. Just to make sure my question, I wonder the operating current of IC itself in worst case(max value, not typical). The total power consumption consists of two major factors : the operating current of IC itself and the output current drawn by MOSFET loads, which can be calculated with Fsw*Qg. I'm wondering about the former factor. Could you please let me know the operating current of IC itself?

Thanks a lot!
